Owner: City of Toronto

Contracts 2 & 3: In procurement
Environmental Services: United Soils Management (soil disposal
subcontractor)
Funding: Public
Substantial Completion: 2026
The City of Toronto, with support from the Government of Canada,
is making a significant investment in stormwater infrastructure to
protect the Fairbank-Silverthorn community from basement and
surface flooding. The project will construct a three-kilometre long
and 4.5-metre diameter storm trunk sewer, 17-km length of storm
collector sewers and install 325 inlet control devices to control
stormwater going to catch basins. When construction is complete,
the new infrastructure will help to reduce sewer backups and
basement flooding for more than 4,645 homes and provide flood
protection to a 140-hectare area. The first contract to construct the
storm trunk sewer and some storm collector sewers is underway.
Several shafts have been completed and others are being
constructed in anticipation of tunnelling work, set to commence in
early 2023.

UPDATED INFO:
The City of Toronto marked a major milestone for the Fairbank
Silverthorn Storm Trunk Sewer System project, launching a tunnel
boring machine that will work to construct a new storm sewer that
will collect, store and move stormwater from the Fairbank-Silverthorn area to Black Creek to help reduce the risk of basement
flooding.
The first section of the 270-tonne tunnel boring machine will
be lowered into a 40-metre-deep shaft inside Fairbank Memorial
Park, located on Dufferin Street south of Eglinton Avenue West.
There, the tunnel boring machine will begin constructing a threekilometre long, 4.5-diametre storm sewer. This project spans four
City wards: Toronto-St. Paul’s, Eglinton-Lawrence, Davenport and
York South-Weston.
